Description High−Voltage Switcher for Medium Power Offline SMPS
The NCP1027 offers a new solution targeting output power levels from a few watts up to 15W in a universal mains flyback application. Our proprietary high-voltage technology lets us include a power MOSFET together with a startup current source, all directly connected to the bulk capacitor. To prevent lethal runaway in low input voltage conditions, an adjustable brown-out circuitry blocks the activity until sufficient input level is reached.
Current-mode operation together with an adjustable ramp compensation offers superior performance in universal mains applications.
Protection wise, a timer detects an overload or a short-circuit and stops all operations, ensuring a safe auto-recovery, low duty cycle burst operation. An integrated, auto-recovery, Overvoltage Protection permanently monitors the VCC level and temporarily shuts down the driving pulses in case of an unexpected feedback loop runaway
